Canada Immigration Questions

Hello, Experts:

I have two question.

1)I sublitted my application to Buffalo and got a letter last June which notified me to have an interview in Detroit. I visited theit web site of Detroit last Month. I didn't find my case number in the list called "Case Received But Wait for the Interview". It has been more than 12 weeks since I got the notification letter in June. Following the instruction in their website (They suggest to send a fax to Buffalo if I cann't find my case number 12 weeks after I got the notification letter), I sent a fax to the Buffalo center to tell them I didn't find my case number. But after their latest update of their list, I still couldn't find my case number.

Could you tell ne what happened?

2)Also I remembered the office said they put my application in a queue waiting for transfer and they will notify me once my file is transferred. The office will send me another letter two months ahead of interview date.

Do you think I can get the letters once they transfer my file?

Thank you very much.
